SAN FRANCISCO (KCBS) – Transbay buses across the Golden Gate Bridge will follow modified routes, and ferries between Marin and San Francisco will run more frequently, during the upcoming weekend closure of Doyle Drive.

Golden Gate Transit routes 70 and 80 will run shuttles between the bridge and downtown San Francisco that detour around the Doyle Drive construction via 19th Avenue and Geary Boulevard.

The 101 route will run as far south as San Rafael before diverting across the Richmond-San Rafael Bridge to use Interstate 80 and the Bay Bridge to enter San Francisco.

KCBS’ Bob Butler Reports:

The new routing begins at 8 p.m. Friday when crews start demolishing Doyle Drive, said Mary Currie, spokeswoman for the Golden Gate Bridge and Transportation District.

“If you can stay away, stay away. And if you need to get into San Francisco, I’d suggest the ferry first. And then we will have the bus system in a different segmented routing,” she said.
